The special Rio+20 episode of Hungry Planet takes us from Bangladesh, where rising sea levels and increasingly severe storms threaten millions of farmers living along the country's southern coast, to Chad, where unpredictable weather patterns fuel hunger and malnutrition, and finally Ethiopia, where distribution of high yield root and tuber varieties help farmers increase production in times of drought.

Hungry Planet is a web-based television series about global food issues and agricultural development. Each episode takes viewers to remote locations around the world and tells the stories of real people - farmers struggling to increase food yields while adapting to climate change, families on the run fleeing conflict and famine, scientists and aid workers on the frontlines searching for solutions that will ensure there’s enough food to feed a hungry planet now and in the future. Stories are produced by the United Nation’s three food agencies – the World Food Programme (WFP), the Food and Agriculture Organization (FAO), and the International Fund for Agricultural Development (IFAD).
